A remote or central computer that holds electronic mail (e-mail) messages for clients on a network is called a mail server. A mail server is similar to the post office, where mail is stored and sorted before being sent to its final destination. When the user requests his or her e-mail, contact is established with the mail server, which then delivers all stored to the client's computer.
What is my mail server address?
Your mail server address and other information should be provided by your e-mail provider. Typically this information is either found on the e-mail providers support page or in documentations from your e-mail provider. When looking for the information you most likely want to find the SMTP and POP3 address information. Unfortunately, we cannot give you this information because every e-mail service has different address information.
If you are the e-mail provider or run a server providing the e-mail service, the mail server information is found in your server e-mail configuration, daemon settings, or through your client portal or Control Panel (e.g. cPanel).
